Hi Maciej & Jürgen, I have updated the PS2 patchset to v4.15 now. For the initial submission, I'm hoping to include device drivers for USB and serial support. The first 20 or so patches are ready for review, with 5-10 additional patches needing clean-ups. USB maintainer Alan Stern has previewed the PS2 OHCI driver: https://marc.info/?l=linux-usb&m=151198476018400 Simple devices such as a USB keyboard work. Jürgen Urban has reported issues with USB mass storage devices, possibly due to lost interrupts. I tried a wireless AR9271 USB device. It had at least two problems: First error was "ath9k_htc: Unable to allocate URBs", due to the (very) limited amount of reserved IOP memory (256 kb). I then adjusted a few hardcoded ath9k_htc buffer limits. The following error was "ath9k_htc: Target is unresponsive" which remains to investigate. Jürgen: In ps2_uart.c for v4.15, the init_timer call needs to be replaced with timer_setup. Work in progress: https://github.com/frno7/linux/tree/ps2-v4.15-n0 Fredrik
